RESUMO
Several expeditions were carried out to four localities [Al-Madinah Almonawarah, Tabouk region, Al-Jouf and Northern Frontiers regions] in Northern and Western Saudi Arabia for sampling zoonotic cutaneous leishmaniasis [ZCL] cases from patients and rodents. Biopsy samples were collected from 51 patients complaining of skin lesions, most of which [40 or 78.4%] proved to be ZCL. Amastigotes were detected in 33 patients [64.7%], but only 30 [58.9%] gave successful growth of promastigotes in the culture media. The positive cases were Saudis 14 [35%] and non-Saudis 26 [65%].Five species of rodents were caught, Meriories libycus, Psammomys obesus, Rattus rattus, Jaculus jaculus and Hystrix indica. The first species was the most dominant [90%] in which Leishmania parasites were detected. The Leishmania isolates from man and rodents were identified by isoenzyme electrophoresis and proved to be Zymodeme LON-4
